The roller, which is an important part of the belt conveyor, has many kinds and large quantities and can support the conveyor belt and the weight of the material. It accounts for 35% of the total cost of a belt conveyor, which produces more than 70% resistance, so the quality of the roller is particularly important. It has two kinds of steel and plastic.
* Through quench-tempering processes to ensure excellent mechanical properties, high strength, and superior wear resistance to bending and breakage.
* Surface hardness HRC40-55 for reduced wear and longer life, adding value to your products further to your business by maximizing the durability of your products.
* We take pride in the quality of our track rollers. The excellent heat treatment processes and our experimental basis of mining, the high quality floating seals and bearing lead our company to produce heavy-duty type and much more durable products.
